MATLAB: Simulink; Without success while applying the ‘Transpartent’ option in the ‘Edit Mask’ functionality

edit masksimulink

Dear Reader

My problem: I have created a subsystem in Simulink and I am applying the Edit Mask functionality in order to load an image and to make it transpartent in order to see my input and output labels.

1) In the 'Edit Mask' editor I have selected in the command line 'image'. 2) I wrote the command 'image(imread('R.png'))' in the 'icon drawing commands' block. 3) I selected 'Transparent' in the 'Icon Transparency' option. 4) I selected 'Pixels' in the 'Icon Units'.

Unfortunaltely, the picture is not transparent and the pictures size is normalized and not as big as the original pixel size.

I am very pleased for any help. Kind regards Lukas

Use the port_label function after drawing the image, to overlay port labels on top of the image. I'm not sure why the icon size is not being correctly applied - you could try contacting Tech Support to report it.

Try this

x = [1, 1.5, 0.7, 2,0.2];
y = [-2, 3, 7, 10, 4]; % <<==== 5th element is added to y to make it of same length as x
labels = {'apple', 'orange', 'plum', 'strawberry', 'apple'};
x_points = movmean(cumsum([0 x]), 2, 'Endpoints', 'discard');
b = gobjects(1, numel(x_points));
ax = axes();
hold(ax);
for i=1:numel(x_points)
    b(i) = bar(x_points(i), y(i), 'BarWidth', x(i));
end
legend(labels, 'Location', 'northwest');

Setting the "Icon Transparency" to "Transparent" should show the port labels underneath. Alternately, you could use the port_label function to draw port labels to overlay them over the image.
